Remove contents of an array from another array

Question

I have two arrays

var array1 = new Array ["a", "b", "c", "d", "e"];
var array2 = new Array ["a", "c", "d"];

I want to remove elements of array2 from array1

Result ["b", "e"]

Is there anything like

array1 = array1.remove(array2)

Note I'm using jquery-1.9.1

possible duplicate of JavaScript array difference

function difference(source, toRemove) {
    return source.filter(function(value){
        return toRemove.indexOf(value) == -1;
    });
}

NOTE: Array.prototype.indexOf and Array.prototype.filter are not available before IE9!
